T1 !Show us what you have for the end of the rubber manifold to carb connection. Must have both metal parts, inside and outside to get a tight seal. Number 24 and 28 on your IPL.

Thanks mate, I won’t be using this carb again!! In future just put some thick very pliable rubber matting between the carb for the saw. Then I will pressure test through the spark plug hole with an adapter I madeThe recessed face of that carb is your problem, you need to use the correct carb to effectively seal against the manifold for a pressure test.

It’s all OEMI usually use a stripped down carb block so I can easily plug the pulse hose below the carb and double up on your rubber if you have to, is that an oem boot or aftermarket?
Have you got a pic of the one you made? I made one from 6mm perspex to then realise the threads don’t run all the way down haha.An old carb makes a good blocker but don`t trust it to block the impulse line unless the nipple on the carb is blocked solid. I have a blocker plate for every application I ever encountered made from 1/4 " thick aluminum plate, when using a plate I can pull vac through the impulse hose. Stihl makes a special adapter, you should get one....LOL
Awesome! I’ll check it out May just get some copper tubing and a set of washers myself too. I’ll check the price thanks again!I use lengths of 1/4"steel tubing cut to span from the threaded portion of the studs down to the 1/4" thick blockers, a washer and nut on each stud to tighten it down and you are good to go. There is at least 2 and maybe more blocking adapters Stihl offers for regular carbs, maybe even more for the newer offerings. For the 026 up to the 066 the part number is 1128 850 4200.

Hey I used an old plug and a rubber oring, just gently snugged. I did find though when I span the crank the gauge moved way more than it does from the impulse or the air intake. Not surprising when you realise that it’s the compression area but I did get concerned it was going to mess my gauge up.When you made the adapter for the sparkplug what did you use? I have made many of them from old two stroke plugs, they must have the flat crush washers ot a tight fitting flat rubber washer to seal effectively.
Some of my blockoff plates have a nipple installed in them but they are for older saws that did not have a separate impulse line. I may pick up another Stihl adapter sometime, my first one got lifted out of my tool box when I was working at a dealership/repair shop along with several other tools, they finally fired the truck driver.
