Im sure whatever lube was used on the primer was not the right stuff, as it was so stiff it was hard to operate, but this kit did the trick! It works super smooth and easy now and the kit took all of 5 mins to install.

PRIMER OVERHAUL KIT

Worked like a champ. My primer was stuck and would not move without pulling super hard. Even when I pulled it out to replace the o rings I was worried about messing something up. Followed the directions. Reinstalled and it moves with almost no effort. I have never had a primer move so easy. Now I have to make sure the primer is actually locked in place. Awesome product and easy remedy.

Great Kit to keep in the glove box.

o rings seem smaller than previous but the old ones are probably swollen. will be trying soon once primer system is closed up and operating.

PRIMER OVERHAUL KIT

Exactly what my cutlass needed. Priming was always difficult stiff to pull or push. Very easy fix. Remove primer nut and extract plunger. A little fuel will come out so be prepared. Replace o-rings lube and what a difference.

PRIMER OVERHAUL KIT

This product had the o rings and lubricant for a reasonable price. Do not order anything from Spencer Aircraft. They charged me $16 to send one small o ring. When questined they would not send it by USPS and they send everything by FEDEX!

PRIMER OVERHAUL KIT

Highly recemmended! Works great, easy to install. Be sure to clean your primer, not just swap the seals and lube. The sticky dirt buildup was nasty.

Easiest maintenance item ever. Nicely packaged with clear instructions.

PRIMER OVERHAUL KIT

Perfect kit. Great price for not just a one time use but for a continuance use of the lubrication. The o-rings are a one time kit which would be nice if they had multiple but understandable since typically owners only have them changed once a year or one every other year.

Exactly what I needed, very much appreciate the instruction sheet.

Helpful sales lady

Havent yet installed this primer overhaul kit in my 172D, but I put the primer overhaul kit in my 150G and it was perfect.

The o-rings were the correct size for a perfect fit. Very good and detailed instructions.

Judging from the squeaking that was eminating from my primer prior to the installation of this kit the primer orings had not been lubricated in many years. With the cold weather, the operation was only getting worse. After the installation of the kit, the primer operation is far easier and no more squeaking. The lubricant that comes with the kit is likely enough for a lifetime supply for re-lubricating it which the instructions recommend on a regular basis.

Excellent kit with good instructions. It included the two O-rings and silicone lubricant. But now that I know how to do the overhaul, I would probably just order the O-rings next time.

Was an easy fix for a leaky primer. Was only a few minutes and had great directions. Would buy again and sooner than last time!

Worked fine. Includes lubricant. EZ fix. Hope it lasts!

Good instructions, super simple fix to a frustrating situation.

Fast and easy installation with good directions. Primer works like new.

fast shipping. worked as specified.

well worth it

The kit worked as advertised!!

Exactly what I needed and it came with a special fuel resistant lubricant that is a must.

Just what I needed

Makes the primer better than new. Owners and pilots are amazed that their primer works so well after I redo their primer with this kit. Many did not realize that their primer was so stiff, they thought it was supposed to be hard to push in and out.

Easy to install and fixed the problem

1965 C 172 F. My primer was dry, rough, and wouldn’t hold prime for start ups. 10 minute installation with this kit, and my primer worked like new again.

This kit was exactly what I needed. For a couple of months, the primer in my C150 seemed to be doing less and less and eventually, it just stopped. The kit was simple enough, just two O-rings that restored the seal and now it works like it was supposed to work. The directions that came with the O-rings were perfect. Thanks

Worked very well. Use a small pan (ie dish pan) underneath just in case it drips fuel when you remove the plunger.

I used this kit to restore my primer. Took all of 10 minutes. An easy fix for an annoying problem. Primer is now as good as new.

Simple and fast overhaul. Well worth it.

Easy, inexpensive fix.

Works great and good value

Great instructions and very simple to installl

Works great

Excellent instructions a large amount of fuel lube easy-peasy

Cessna Cardinal 177B. Found primer with no vacuum/loose before recent flight. Purchased kit after research. Easy installation (30 mins). Primer back to normal operation. Enough o-ring lube for further periodic preventative maintenance. Not everything is expensive to repair!

I havent used this one yet, but I purchased and used one a few years ago for a Cherokee 140. It was very easy to install the o-ring and lube the cylinder. Afterwards it worked like a new one - cylinder filled with fuel and moved smoothly. I periodically lubed the cylinder to keep it moving smoothly. A very cost effective solution that I am sure will work great on my Cessna 182.

I will never be stuck again with a hard starting engine due to poor or no prime. I bought 2 of these kits, installed one and stashed the other in the plane! Good value too!

Saved my primer. Works great. Lubricate primer plunger often for years of continued use.

Well worth the money. Kit makes your primer system work like new! I recommend lubricating the o-rings every few months, or as soon as any resistance is felt.

Very simple and easy to install . The instructions were precise and easy to follow
