Spuds Porting and Tuning Thread

[spudulike]

It still as good as ever Steve ! Just kidding mate .

 

It helped sortig out that breather hole in the inlet manifold - real strange one to have an original part with a manufacturing fault like that:thumbdown:

Mines is an absolute loony it's on an 18" bar but pulls like hell....no one will stand close enough to record it cutting because it's to loud ticking over its louder that my 171 and 135 at max revs!!!

Been using my 357 this last week. It's absolutely mental! Is it normal for the cylinder fins to become spit sizzling hot?

 

It conked out a couple of times after some hard work, and didn't want to start, pullover feels smooth and compression is still good, and plug colour is biscuit brown.

 

I'll get a new plug for it and see

It will get pretty hot especially if the piston has been swapped for a new one and the engine is bedding in like on yours. It has been set up correctly so should be fine.

 

The porting makes the saw run much richer than normal so I retune the carbs to between 3/4 and 1 turn out on the H screw. Sometimes they can run a little rich and this can cause hot starting issues - not that often but had it on Stubbys 346 on an 8 pin rim - the extra load was bringing the revs down and the extra fuel caused issues until I leaned it up a little more.

 

If it happens after a long run, let the saw idle for a little after the run to clear any excess fuel.

 

Other than that, difficult to say, check the plug colour!

 

Sorry - just seen it is biscuit brown!

[Joe Newton]

I usually let the saw idle for a while before switching it off

 

I'm gonna get a 15" bar and 8 pin for it, should be a giggle

 

I'm saving up for a 372 for you to have a play with in the future!

Tried the 034 today, it seems pretty good, the pickup is way better. Cheers Spud!

Good, glad you like it, the 034 is a bit like the 460 and 440, you do lots of smaller adjustments all over the engine to come together to make a decent difference. It did seem way more sprightly when revved than before.

Just got my 460 back from the saw Dr and tomorrow it is getting put to work. Quite excited because when I picked it up spud decided to disturb his neighbours, it sounds fantastic and picks up very very quickly.

Still ok Steve? It's had a few tanks through it and it's still bonkers
