Put after run oil right in to the venture and not the fuel nipple as if you put it in the fuel nipple it could affect the o-rings on all your needle adjustments. When I but the after run oil in mine I take out the glow plug put 2 or 3 drops right in to the cylinder and 2 or 3 drops in the venture then turn the engine over. Put the glow plug back in put a couple more drops in the venture and turn it over again. I have found unless you put to much after run oil in my engines start easier after using after run oil because has a little more compression and lubes everything well to make it turn over better.

tattguy12 When I change the engine is my Savage I am going with a STS .28 for two reasons. One I hope to race sanction racing and the biggest engine you can run is a .28. Two normally as the engines get bigger in size means a longer stroke and normally makes the RPM lower which gives you less top end but does give you more torque. One other thing on the STS I recommend sealing the engine before you install it. I have an STS D21B for my buggy I am going to break in next week.

I forget who it was on here having so much trouble with there T-15 and if you remember I said I had one I was working on for a friend that we could not get tune properly. Will I sealed the engine and it is running better then it ever has!
