Brewz Saw Builds

Nicely done. That carb have a ball and spring style limiter like the dolmars or a fixed jet?

As for starter handles, sheared a d handle in half myself today.

Mate I really don't know to be honest and cant seem to find any detailed info on the carbs.
I start winding in the H to lean it out, and it gets to a point where the revs stop rising and then it sounds different like its being clipped so I assume its the limited coil holding it back.
It runs with the flywheel on the limited keyway.

Now that its been ported its blubbering rich on the limiter so needs a couple thousand more RPM.

I have the 088 that came with the 084 which has an unlimited coil and I can lean that right out no problems.
When I get the 1308 unlimited coil, if I cant lean it right out with the carb on the 084, I will try it with the carb on the 088

The ht5 is limited. I have one and need to figure out how to block the overflow curcuit

 

[mdavlee]

Ht 1 and ht 7 I believe are non governed.

I will have to pull the carb off the 088 I am going to flip and see what it has on it

sorry been playing 4x4 the past 5 days. if it does fire in the wrong key it will sound terrible and wont run. pop it int he other keyway and bam!

Thanks vince

Just got home from work and look what I found waiting for me @jockeydeuce

Carb on the 088 is a HT 12 with limiter caps
I wonder if it would be limited if I pulled the limiter caps?

Had a dig on the tillitson website and found a parts list for HT 5 and HT 7

The 5 lists a "remote fixed jet" that is not listed on the 7

Now to find this jet and make it smaller

3 screw 1308 unlimited!!

Yeah baby.... YEAH!!

Is that on the bench to be ported now Jay?
I would be very interested to see what you do

I don't think the 12 is limited. I'll search for the IPL on the 5 to see if the jet can be found.

Soon as a piston gets here it will get ported.

I'm not sure that a low exhaust is needed on these,96-98 will probably work.

That would be awesome!
I really appreciate people's help and knowledge sharing with this stuff

I can't find anything else online with a good diagram. There's pictures on AS in a thread that shows the extra jet. Thinking we can just plug it with something and not use the auxiliary jet to flood it.

What are you thinking with the intake?

I will pull it off the saw after dinner and get some photos

The H needle seems to be seating so the fuel must be bypassing this



Here is the top
I tried to unscrew the jet with the slot in it but it won't move



Both the brass jets protrude into the centre of the carb but the one with the slot and hole in it doesn't seem to have a hole in it





The hole on top over the H jet sits where it can flow in
I'm guessing the brass jet with the slot is the fixed limiting jet.



I might order some little drills so I can find the jet size and try filling the hole with solder and drilling in a smaller jet hole
