Question
Hi Eric!  I pulled apart my 2005 Husqvarna 340 saw and replaced the piston.  I noticed that there was what looked like a silicone gasket between the crankcase and the cylinder.  I have not been able to find a silicone gasket material rated for use with fuel.  Would you happen to know what type of material I can use?

Thank you,

Seth

Answer
Did you get a new gasket?  A gasket should seal just fine but you could use Copper SPRAY-A-GASKET Hi Temp Adhesive Sealant or ULTRA COPPER Hi-Temp RTV Silicone Gasket Maker.

Never used with on a jug gasket but it not might hurt.

What color was the old silicone?

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
