I usually don't either and didn't on the SP70. I was going thru the manual this pm and that's what it said. think I will just leave them dry.
thanks guys.
The only time I've used sealant on a carb gasket was when I had a Tilly HS that was pretty out of true on the carb body and had a minor air leak. I lightly smeared a thin layer on that exact spot and that fixed the leak, but outside of something like that I wouldn't try it.
 
had to give my daughter a hand this morning but I had the 10-10S on my bench ready to put back together. antsy all morning. anywho, got it done and it would not start. thought it was still the ignition but put the spark tester on and had great spark. pulled the plug and dribbled in some gas and it fired right up and died. did it again and this time it kept running. yahoo.

when I did the SP70 a few weeks ago it fired on the 2nd pull and ran on the 3rd. this 10-10 I pulled 20 times before I dribbled gas in, and it fired. here's my theory: the SP70 has a Stihl type fuel filter with a screen and weight on the fuel line. the 10-10 has a brand-new fuel line with the cotton or whatever it is filter. I suspect it was taking some time to get fuel thru the cotton into the line and when it fired on prime the vacuum sucked the fuel thru to the carb.

this thing is loud! it has more compression than the SP70. the auto oiler works great, as does the decomp. got one issue though. the throttle is sticky and returns very slowly. it's in the trigger. going to have to drive out the trigger roll pin again I guess and figure that out. not usable as is.

I always cheat... I keep a squirt can of two stroke mix and shoot some up the muffler, makes them pop, and they pull fuel faster. I say cheat, cause thats what Bob J calls it. I call it "save my shoulder" lo. Congrats on the 10-10S good saws
 
Today's weather here in W.N.Y.was fantastic for late Oct.! Temps in the low 70's.I had my son pull the log splitter up front so I could work on the carb.I had a new carb put on back in July & it was trouible from day one.The shut off linkage would come unhooked from the carb.I had to put a screw down through the plastic shaft the the linkage hooked onto,now it works great.Meanwhile,I had my son mow the back lawn & mow down the weeds in the garden.
The weather is supposed to continue to be fantastic through Wed.next week,so I'm hoping to be able to work on the PM55 again & maybe finish it.
 
The slow trigger could be where the linkage goes thru its little boot under the stop switch. Try spraying it with something before tearing it apart. Ive had that hsppen once. Took it apart 3 times and it was still sluggish on returning. Sprayed a carb cleaner on that rubber boot for the linkage and it frred it up. Lubed it with wd40 and no issues. Just a thought.

I'll give it a try, but I think the trigger was a little sluggish before I even connected the linkage rod. I thought it would loosen up and that the spring on the carb would help. should have known better. thanks for the advice.
