Push lawn mower shafts went from 1" to 25mm

I had to buy a blade for that thing,cost me a whole 7 bucks .Now that wouldn't have annoyed me so much if it weren't for the fact I must have a dozen 14" metal cutting blades with 1" holes for the two electric cut off saws I have .I'm a cheap skate ,what else can I say . ;D

Just so happens I am working on one of those at work right now.   
Someone had stripped the plug out in it.   So I pulled the cylinder off of it so that a helicoil can be put in it.
The cylinder is made by Gilardoni and is a quad closed port transfer design.   I also did a check of the squish without the base gasket and measured .023".    I measure the base gasket and it was .020.
The shop I work in had a guy there put the helicoil in the cylinder and I have to say he did a really nice job on it and your right it does use a really small peanut plug.    I have not finished putting it back together yet but It will not take long now that I have the cylinder back in place along with the intake and carb.

A quad transfer would be on the order of a Husqvarna .It would make sense that being the case it should have enough power I would think .


Well a concrete saw .If it were cheap enough like the two I got if you only used it several times as oppossed to a portable circular saw using abrasive blades it would more than pay for itself .I'd about bet one of those 14" abrasive blades would do more than a dozen 7" or 8" "Skil saw" type blades .An impregnated diamond blade with water coolant would probabley out last a 100 of them .

The Honda generator uses a NGK CM-6 which is 10mm but a shorter reach. All the newer design model air plane engines use a CM-6 plug

The NGK plug you mention is in the new husky 545, 500, etc
