McCulloch vacuum pressure block off plates.

[YoungSawman05]

Hey fellow Mac enthusiasts!

Was wondering if there is anywhere to buy/ idea to make a block off plate for the exhaust and carb to get a vacuum pressure tests similar to my Stihl tools that block off the intake and exhaust. I have read a few things in the Mac threads about people making them. Was wondering if anyone sells them / guidance on making one. For a PM850, PM700 and PM 10-10s that I want to keep running forever. I also just like to collect tools I might use once a year

Some 1/8 rubber sheet material and aluminum plate 1/8-1/4 thick with holes to match the intake and exhaust pattern and sum screws to match , fairly easy,

I work in a steel mill. I cut a bunch of plates and just drill the holes for the muffler bolts. Bicycle inner tube rubber works well.

Been a minute since I did that on an old McCulloch but I believe I did it like you can on most modern saws. Make holes in a piece of 1/8 rubber . and bolt the muffler/carb down over it.

I bought a set from eBay some time ago, not sure if they are still available.

Check with member cinci5 here on OPE. He was making and selling them on eBay but does not have them listed currently.

Alternative is to cut a solid "gasket" from rubber (inner tube, etc.) and use the muffler and carburetor to seal the openings.

I just use a piece of inner tube and use the muffler and carb to block them off.

Somehow this winter I ran a bolt in a rear tractor tire. I had the on-farm tire service guy out to put a boot in it and a new tube. The new tube was $89. As he was cleaning up he was going to put the old tube in the service truck. I laughed and said "I have have a use for that"...... and tossed it on the nearby trailer. Lots of material there.

Loooking for a set of tools to pressure vacuum test a variety of Mac saws for future repairs.

It'll be in June because I'm away from my mill but have other products with me for eBay. I'll make a few sets and re-list them.

The Echo service tool rubber block off plates are not model specific and cheap to buy, like 10 bux. I've never found a 2 cycle engine I couldn't use them on.

I would love to see a set of those....$10 and fits all 2 strokes

 

[FergusonTO35]

I should clarify, 2 stroke engines in my fleet which would be saws and weedeaters 20-50cc.
