zdz40 plug wet
Hi I have a zdz 40rv from new and firstly it is brilliant been no bother to start and pulls my Gp yak 54 around with mega authority on a mejlick 21x8. Now my plug is wet and slightly oily, but the engine ticks over well holds full throttle without sagging. Ive noticed that the throttle up is slightly slower than previous so is this an indication that iam too rich on the low needle. As i say it a brilliant engine just after 4.5 gallons its gone a bit rich maybe! im not sure..
