Spuds Porting and Tuning Thread

[spudulike]

Yup, one of three I got from a local gardener, all non runners, fixed all three, sold two and ported one for me. The strimmer also has a muffler mod

you have any videos of the 660 with that exhaust running?

No, not yet but it is about the loudest saw you are likely to hear.

how fast does it cut?

Yes, my own BG85, goes like a good one and has plenty more clout than standard:thumbup:

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

Has anyone ever ported a leaf blower?
I’ve got an old echo es2100 that would benefit from a boost

I'd like one for when the hot air balloons start coming over, stop 'em spying on me the beggars

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!

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.
