It has fresh gaskets n my parts guy up at earlys said with my fresh gaskets its fine n I run a 340 main on a stock 26 mil carb
What you need to do to have chance to solve your problem is to do the following ......
Compression test.
Then leak down test. Do it yourself, it should hold 7psi for 10 minutes.
Toss that octane booster, it is taking the place of precious 93 octane fuel which your mods should run fine on.
Mix a good quality 2 stroke oil at 32:1.
Do a leak down test, just in case you forgot to do one, then do a leak down test to make sure you did it right.
A #340 main jet with your stated mods would just about run your motor in the depths of the Atlantic trench.
Post your findings after you have done a leak down test.
By the way did I mention that you should do a leak down test.8-|
Another thing you might like to try is to pull the flywheel off and see if the key is broken.[/QUOTE
I run 32:1 with either lucas 2 stroke mix or yamalube sometimes redline
will do and dad told me he needs to get his air tools back so we can advance my timing a little bit more but 30 mil wouldnt help at all..cause when its tapped on topend it wants more gas but it floods on bottom end
you should not need a air tools to do a timing adj. YOU SHOULD NOT USE ANY AIR TOOLS ON A BLASTER MOTOR AT ALLL. Maybe in some cases.
BUT NEVER ON THE END OF THE CRANK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I wanna pic of that leak test!!!!!!!!!!
throw the octain booster across the yard. YOU DONT NEED ITTTT!!!!!
Im almost garenteeing you your 340 main jet is WAYYY TO BIGGG!!!!!! unless ur under the ocean, where theres air.....:-/
advancing your timing with make your knock WORSE!!!!
NOW if your motor runs best with a 340 main your motor is eather hauling ass!!!!! with a stock design head.......8-| OR YOU HAVE A MOFO AIR LEAK MY SON!!!!!!!!!
Liston to the advise givin to you^^^^^^^^^^^^^^
with my experience im guessing your head is whats givving you most problems. BUTTT your super octain booster should make up for it. BUT since it isnt you got problems my friend..........
just a thought.....
i use ait tools to take the bolts out that hold my cases and side cover on
that would be one of those in some cases .....
