Spark plugs 200efi. CDM ignition. AND I NEED A THROTTLE BUSHJNG!
I am hearing I should be running BPZ8HS-10 in my 200 efi CDM style ignition.
Bu8h are what was installed by the so called "engine builder"
its skipping and piping randomly at idle.
I can't get it smooth below 1200 rpm on land and 1000 in the water in gear it will still pop randomly.
Also. This guy broke the throttle shift bushing. So I have it held together with a washer
mid anyone has one laying around I would gladly pay for it and the shipping.
I am trying to get this thing together for Labor Day so I'm reaching out for a little help on both these things.

whats a throttle shift bushing??-th

It's the bushing that I have never seen break or wear out in my life but this guy broke mine and actually put it back in. The throttle and timing linkage are held in place with the bolt through this bushing so they can pivot when you throttle up.
The arms were working there way off over the bolt. This guy could have really gotten someone injured with his shoddy work. Every system he touched was Damaged,broken or left loose.
This is a 5.00 bushing!??
I orderd one but beware check everything!! Thank god this thing ran so poorly when I got it. Back I had to scour it for stuff just like this.

Is it stock compression? If it's raised to 140 ish need to go to colder plug. Which is a bpz9hs-10. If stock 8hs is correct

I actually ran B9HS 10 in my head gasket cdm ignition with no issues. (B8HS 10 if stock compression). Not sure what the difference is with the bpz and b plugs are in case it is a difference in the two style heads(O-ring and gasket). Didn't think cdm came on head gaskets motors only o-ring. I replaced my o-ring block with gasket block and used b9hs10 plugs.

From what I'm seeing the p after the b is for projected tip which moves plug deeper in combustion chamber and z is for inductive suppressor. Need to make sure the pz plugs are not too long for the head gasket motor, may only be for the o-ring heads. I personally would run the B8HS 10 plugs with gasket motor as long as stock compression and 9 if raised compression.

My 03 runs like a dream at 140 psi .015 over, wsm pistons on the "z" 10' s , 170 hours on it now, i fouled a plug one time and installed 6 new non Z plugs and it missed and backfired at idle on the hose. Put new Z's back in it and ran awesome, cdm alternator were happy with the suppression plugs.most reliable fishin motor ever that 200

The only plugs my 03 efi with 140 psi has ever run on is Z 10's, i rebuilt it at 480 hours, 3 yrs ago,170 hours,virtually no leakdown, it even sank once on a boat and was fully submerged 7 hours.boat was goin down fast and she got me to shore, only cause of the downdraft intake, i killed her before water got that high, , I only run 91shell v power in it, and prem. plus on the auto oiler.

10 is not the heat range 1st number is. The p is what has to be considered with head style to make sure not too long. Has nothing to do with cdm. The z is for suppression type which could follow cdm.
