how fast does it cut?

Up until a few weeks ago, the ignition timing was wrong so not well but got it set to 30 degrees and should go a lot better now. Carb tuning is weird and think the expansion has had a fair bit of effect but need a big lump of timber to try it on now!

Excellent, so what did you alter?
Is a basic exhaust mod worth doing or are we in the realms of advancing the timing?

Widened the ports, dropped the base gasket and opened the muffler a bit - didn't want it too loud, neighbours wouldn't like it!!

That sounds beyond my mechanical skills lol, I was considering a muffler mod but if it’s going to need a full port to make any real gains I may have to pass it on to the expert.
can you pm a price please?

TBH, the cost of doing the work probably outweighs the advantage and will be a large percentage of the new cost of the blower. The Echo blower probably has a CAT in the exhaust, drill it to bypass the CAT and retune the carb - should get it going better.

Thanks spud, appreciate all your comments mate[emoji106]

A quick update on my blower. It was easier than I had thought, didn’t even need to drill the exhaust.
Unscrewed the exit housing on the exhaust, there were two baffle type plates like you’d get between the cylinder and exhaust on a saw. Removed the spark arrestor, put everything else back on minus the upper plate and it has given the blower a new lease of life [emoji106][emoji106][emoji106]

Good, glad it worked out. Is that 660 still bopping - that was a few years ago!

Yes that was a few years back, still going strong mate, I fitted a dual port last year, it’s quite noisy lol

That's good, glad it is still putting in the work!

Does the meshy type filter from a 200 fit the 201tcm instead of the "papery " type?
